I made geek cookies!
Yes, those are Erlenmeyer flasks, beakers, and test tubes. The set of cookie cutters includes an atom (well, in the symbolic sense), but I was making cookies for a pile of medical lab techs, and we're more about the test tubes.
I almost made them red, because we all handle tons of blood every day, but I figured no one would eat them. Plus, if I got started down that road, I just know I wouldn't be able to resist making some that were pink and chunky from fat, or brown from hemolyzation, or green from... I don't know what, but I've seen 'em. And down that road lies madness and grossness and other such things. So! Peaceful and calming blue it was.
My favorite cut-out sugar cookie recipe is this one
from the Kitchn
. They cut out and transfer easily, hold their shapes fantastically through baking (no spreading), and are soft and delicious. Plus, almond extract! Can't go wrong with almond extract.
